Objective To analyze the composing principles of herbs in prescriptions for treating nervous urinary frequency of children by using traditional Chinese medicine. Methods The prescriptions for treating nervous urinary frequency of children were searched in CNKI, VIP, Wanfang database to establish relevant database, and the composing principles were analyzed by using revised mutual information, complex system entropy cluster, and unsupervised hierarchical clustering in the TCM inheritance system after data entry. Results Based on the analysis of 117 entries in 63 cases of prescriptions, the frequency of 32 entries was more than 5 times;22 combinations contained 2 to 3 entries, including 10 entries in total 11 medicine association rules and their confidence coefficient were obtained, which leaded to 14 new core combinations and 7 new prescriptions. Conclusion Nervous urinary frequency of children is mainly treated with the tonification by Chinese herbal compound, in particular with the herbs which can nourish kidney and reduce urination. The new prescriptions were generated by TCM inheritance system, which need verification through clinical trials.

AIM: To investigate the effects of ?-mercaptoethanol (?-ME) and all-trans rentinal acid (RA) on glial fibrillary acidic protein (GFAP) expression in mesenchymal cells derived from mouse fetal liver in vitro. METHODS: Cells suspension from 14.5-days-old mouse fetal liver were cultured in DMEM/HEPES/F12 supplemented with 20% FCS and mesenchymal cells were acquired after discarding nonadherent cells. The 5th passage cells were induced by ?-ME and RA. The characteristics of treated cells were assayed by immunocytochemistry staining at 5 hours and 5 days after induction. ?-actin as an internal control, GFAP gene expression of mesenchyal cells was detected with semi-quantitative RT-PCR. RESULTS: After being inducted by ?-ME and RA, 80% approximately of the cells exhibited typical neural morphology and about 85% expressed GFAP phenotype. Semi-quantitative RT-PCR showed that mRNA expression of GFAP increased in treated cells versus untreated cells (P

0.05.GFA protein was also detected in skeletal muscle of neonatal and adult mouse by Western blot.The results indicate that the mucsle of adult mouse has the potential to differentiate into glial cells.

Objective To analyse correlated risk factors of evolving cerebral infarction(ECI).Methods The follow data was recorded in the acute cerebral infarction (ACI)cases when they were admitted :sex,age,systolic blood pressure(SBP),diastolic blood pressure(DBP),history of disease (diabetes mellitus,hypertension,hyperlipidaemia,cerebral infarction,hyperuricemia or smoking).The following examinations or determinations were done,including:white blood cell count (WBC),platelet count (PLT),blood gluconate(GLU),PT-INR,fibrinogen(FG),TT-INR,APTT-INR,C-reactive protein(CRP),D-dimer(D-D),products of fibrin degradation(FDP),anti-thrombin Ⅲ(ATⅢ),apolipoprotein A(apoA),apolipoprotein B(apoB),blood urea nitrogen(BUN),creatinine(CR),triglyceride (TG),high density lipoprotein (HDL),low density lipoprotein (LDL),very low density lipoprotein (VLDL),GOT,lactate dehydrogenase(LDH),creatine phosphokinase (CPK),MB isoforms of creatine phosphokinase (CPK-MB),? hydroxybutyrate dehydrogenase (?-HBDH),troponin I(TnI),cerebral CT or MRI and carotid ultrasonography.The patients were divided into two groups,ECI and completed cerebral infarction (CCI),according whether neurons function scale deteriorated.When cases of both groups exceeded 50,we took statistic test by SPSS10.0 statistic software.Results 8 of the above 46 markers had significant defference between the two groups,including CRP,WBC,apoB,GLU,LDH,CPK-MB,?-HBDH and DBP.ECI was more common in patients who had lower DBP or higher CRP,WBC,apoB,GLU,LDH,CPK-MB,?-HBDH when they were admitted.Conclusion The increase of CRP,WBC,apoB,GLU,LDH,CPK-MB,?-HBDH or decrease of DBP when patients are admitted can be predictive markers of ECI.

Objective:To investigate potency of mouse fetal liver mesenchymal cells differentiating into neural cells in vitro .Methods: Sterile cells from 14.5 day old mouse fetal liver were cultured in DMEM/HEPES/F12 supplemented with 20%FCS and adherent cells were acquired after discarding nonadherent cells. The 5th passage cells were induced by ? mercaptoethanol (? ME) and all trans retinoic acid (ATRA). The characteristics of treated cells were assayed by immunocytochemistry staining and semi quantitative RT PCR method on 5 h and 5 d after induction. Results: After induction by ? ME and ATRA, approximately 80% of the cells exhibited typical neuronal morphology;most cells expressed neuronal phenotype such as neuron specific nuclear protein(NeuN), neuron specific tubulin Ⅲ(TuJ 1), neurofilament M(NF M),and neuron specific enolase(NSE).However, microtubule associated protein tau(Tau 1)and microtubule associated protein 2 (MAP 2) as indicators of mature neuronal phenotype were undetectable. Semi quantitative RT PCR showed increased mRNA expression of brain factor 1(BF 1), brain 3(Brn 3), and neurofilament L(NF L) in treated cells versus untreated cells ( P

Objective To evaluated the improving effect of training method of point-line-plane on development quotient in premature infants with brain injury.Methods 174 cases of premature children with brain injury were randomly divided into study group (89 cases) and control group (85 cases).Control group given Bobath and Vojta traditional rehabilitation training,and the study group was given training method of point-line-plane.Patients in both groups were evaluated synthetically based on The Evaluation Chart on Neu-robehavioral Development of Children Aged 0-6 Years,developed by Capital Institute of Pediatrics,prior to the treatment,and after the first,the second,and the third course of the training programs,respectively.Re-sults The score of developmental quotient ( DQ) between study group and control group was no significantly different(P>0.05).Compared with before treatment, the scores of DQ was significantly increased after the first, the second and the third course of training treatment in study group and control group((82.71±12.28) vs (81.17±9.63), t=0.859, P>0.05;(89.65±10.02) vs (87.02±7.39), t=1.747, P>0.05). Compared with the control group, the scores of DQ in study group was no significant difference after the first and the second course of treatment,but there was significantiy different after the third course treatment((95.26±8.87) vs (91.31±7.63), t=2.945, P=0.004).Conclusion The training method of point-line-plane can improve the clinical efficacy of premature infants with brain injury at the early phase, which is worth widely applying in clinical practice.

Objective To observe the effects of citalopram and physical therapy on poststroke depression(PSD).Methods72 patients with PSD were randomly divided into medicine group(n=36)and control group(n=36).The patients in the control group were treated only with physical therapy and the patients in the medicine group were treated with Citalopram and physical therapy.All patients were assessed with Zung Self-Rating Depression Scale(ZSDS)and Modified Barthel index(MBI)before and after treatment.ResultsAfter treatment,the Zung score in both groups decreased significantly(P<0.01).Meanwhile,the medicine group showed significantly less depression than the control group(P<0.05).The score of MBI was also significantly increased after treatment(P<0.01)in both group,but there was no significant difference between two groups(P>0.05).ConclusionCitalopram combined with physical therapy is effective on PSD.

Objective To investigate the effect of clotrimazole on apoptosis of hepatic cells after ischemia-reperfusion injury and its mechanism. Methods Hepatic ischemia-reperfusion rat model was established. Thirty-two male Sprague-Dawley rats were randomly allocated into sham-operated group, model control group, low dose clotrimazole group and high dose clotrimazole group. Apoptosis in hepatic tissue was assessed by TUNEL method. Protein expression levels of CYP3A1,Bcl-2,Bax and PARP were measured by Western blotting. Results As compared with model control group, the apoptosis rate, tissue injury,activity of plasma enzymes and the Bax/Bcl-2 expression ratio were reduced in low and high dose clotrimazole groups. The apoptotic index in both clotrimazole-treated groups was lower than that of model control group with statistically significant difference. CYP3A1 expression was significantly induced by clotrimazole compared to the sham-operated group. Conclusion Clotrimazole may inhibit apoptosis of hepatic cells by up-regulating Bcl-2 and down-regulating Bax, thus produce a protective effect on hepatic ischemia-reperfusion injury and it is also related to the inhibition of PARP shear.

Objective To study the capacity of dentifrice containing hydroxyapatite (HA) particles with various grain sizes on the sorption of Cu (Ⅱ) ion from aqueous solution. Methods Three groups of dentifrice suspensions containing 3% HA particles with 60 nm grain size, 3% HA particles with 12 μm grain size, and blank dentifrice were prepared with serial concentrations. Copper ion solutions with initial concentration of 4.0 mg/L were mixed with dentifrice suspensions respectively and then been kept still for 24 hours. The residual copper ion concentration of the supernatant was measured by inductively coupled plasma emission spectrometer and the sorption rate of copper ion was calculated. Results The residual copper ion concentration of the supernatant decreased with increase of the concentration of dentifrice suspensions. The sorption rate of copper ion of dentifrice containing 60 nm HA was highest among the three groups. Conclusion Nano HA should be added into dentifrice to enhance the sorption capacity of copper ion from aqueous solution.
